This mating pattern and mating net is a variation on the two Bishop mate. The basic elements are:
- the opposing King castled to the Queenside;
- two opposing pieces which block the opposing King’s escape to the d file;
- a Bishop that takes away the King’s escape to the b and c files;
- a Bishop that checkmates along the short diagonal from the a file.
